Application filed October 18, 1913. Serial No. 796,000.

To all whom it may concern Be it known that .I, SVANTE WILI-IELMNILSSON, a subject of the King of Sweden, residing at Stockholm, in theKingdom of Sweden, have invented new and useful Improvements inConstruction of Framings for Supporting Ceiling, VVall-Plastering, andthe like, of which the following is a specification, reference being hadto the drawing accompanying and forming a part thereof.

My invention relates to improvements in latticework framings forsupporting ceiling and wall plastering, which latter may be laiddirectly on the framing, or a lathing, thatching, plaster may be securedto the framing.

The invention has for its object essentially to reduce the cost ofmanufacture of such lattice-work framings, my framing be ingcharacterized by the lattice-work being formed of double wire ties orbraces of a slightly oblique shape and terminating in bent ends or hooksengaging with rods suspended from hooks inserted in the ceiling or wall.This framing is specially adapted for concrete floors, but it may aswell be used for ceilings, walls, or partitions of any kind.

Referring to the drawing which forms part of this specification andshows a specimen of my improved framing, in which like characters ofreference indicate like parts throughout the several views of thedrawing, Figure l is a section of a concrete floor, to which the saidframing is applied. Fig. 2

' is a plan View of the framing, and Fig. 3 is a detail sectional viewthrough line A-B in Fig. 2.

When molding the floor, wooden plugs or the like, 2, are inserted in thebeams or girders 1, and after the concrete has set and the mold has beenremoved, hooks 3 are screwed or driven into said plugs 2. In these hooks3 are placed round iron rods 4, which will thus run along the centerlines of the beams 1 parallel to each other, and from these rods aresuspended the double wire braces 5, as will be seen from Fig. 2. Thebraces are of a somewhat oblique shape and provided at their ends withbends or hooks 6 and 7 intended to engage with the rods 4. The hooks atthe ends of each brace are turned in opposite directions. Thesubstantially parallel wires 5 of which each loop is composed are not infact exactly parallel but converge slightly, as shown in the drawings,whereby Specification of Letters Patent.

the end having the hook 7 is narrower than the end having the hook 6.The framing is put together in the following manner: By means of itsnarrower hook or bend 7 a brace 5 is hooked from below on the right handrod 4 (Fig. 2), and then this end is secured to the corner C by means ofa nail, staple, or the like-8 driven into the wall 9. Then the otherhook or bend 6 of said brace 5 is hooked from above on the next rod 4(to the left in Fig. 2), and this end is pushed along the rod as far aspossible from the wall, so that the brace becomes well stretched.Thereupon the next brace is hooked with its narrower hook 7 from belowon the last-named rod 4, so that it grips the hook 6 of the first braceand enters between the shanks of said brace (see Fig. 3), and in thisway a close connection between the two braces is established. The otherhook 6 of this latter brace is hooked from above on the right-hand rod4, and so on. In this manner the several braces are hooked on the rods 4and locked, each brace being stretched in the aforesaid manner, untilthe opposite corner D has been reached, when the outer hook of the lastbrace is secured to the wall'9 by means of a nail or staple 8. In thismanner a lattice-work is formed between the rods 4, and the plaster maybe directly laid thereon, or a suitable key for the plaster, such aslathing or thatching, may be secured to the braces 5 by means of wirecramps or the like. If the braces are duly stretched the latticeworkwill be sufiiciently strong for supporting even the heaviest plasteringwithout giving away.

The width and obliquity of the braces 5 should be so calculated thatthere is space enough on the rods 4 for hooking on the braces of thelattice-work of next bay. After all the braces have been hooked on, thehooks 3 are driven in entirely, so that the hooks of the braces arepressed against the faces of the beams or girders 1 and thus firmlysecured.

Having now I claim as new and ters Patent is 1. In a lattice-workframing of the character described, the combination of a pair ofparallel supporting rods, of a plurality of double wire braces ofsubstantially rhomboida-l form, the opposite ends of each brace beinghooked over said rods and the hooked described my invention, what desireto secure by Letend of one brace. of the adjacent scribed.

4. In a lattice-work framing of the character described, the combinationwith supporting rods, of double wire braces of substantially rhomboidalform having hooked ends for engaging therewith, the hook at one end ofeach brace exceeding slightly a quarter turn and the hook at the otherend thereof being at least a half turn.

5. In a lattice-work framing of the character described, double wirebraces of substantially rhomboidal form each having one end slightlynarrower than the other end, said ends being oppositely bent to formhooks, the hook at the wide end exceeding slightly a quarter turn andthe hook at the narrow end exceeding slightly a half turn.
